Then you search for what it is you want to buy or who you want to buy from, i.e. chainreaction, merlin, wiggle etc, but also mobile phones, utility switching etc.

You get the kick back that all these companies pay for referals, the % varies (3% from Chainreaction, 2% from Tesco Wine) it sits in an account for you in Top Cash back and once it hits about £50 you can take it out, I've had two payouts totaling about £120 so far.

You can get quite big amounts when switching power and gas, telephone, Sky TV etc, very much worth doing it, I got £50 for switching from Npower to a cheaper fixed deal a week or two ago.

Just make sure you clear your cache/cookies every now and again. I've lost a couple of cashback claims in the last year because apparently another provider had claim to my referral i.e. although I went to the site to make my purchase via topcashback I had previously visited the site via an ad link from another website and they got the credit instead.

I have had over £700 transferred to my account from topcashback in the last 2 years which either makes me very happy that I have made so much back or very sad that I have spent so much to be able to save so much! The best one recently was a £105 cashback for taking out £120 of landlord buildings insurance.

My view of Topcashback is not the greatest at the moment - been waiting on over £100 from 2 purchases since September. One has been confirmed but never paid and the other has still not even been confirmed despite raising a claim.

It's potential free money, so if it was something you were going to buy anyway and you didn't pay a premium going via a referral site, if it doesn't track you're no worse off. Some people seem to lose sight of this...

I use Quidco, not everything tracks but you can put a claim in to get the money owed. I've had just short of £1k back in about 3 years. I normally let it build up to £250 or so the transfer it into my bank account. I've bought nothing I wouldn't have just use whatever works out cheapest. Car insurance is a good one for big money, just taken a policy with Aviva and it's going to payout £80.

Its a no-brainer really.....BUT try not let TCB change your buying habits or just go for deal A because it pays more cashback, basically what i'm saying is cashback isn't always guaranteed! I've earned around £500 in a little over 2 years and i'd say 10% of claims haven't been paid for some reason or other.

Go shopping online and before you pull the trigger check out TCB and Quidco for the bonus ball.

Oh and use a different browser to your main one (Chrome or Firefox) so before you buy you can flush the history and cookies and ensure it tracks (and subsequently pays) properly.

I use mine religiously for hotel booking (usually 10%+ and lots of ad-hoc work related expensable bookings) and insurance cos I switch every year. Day-to-day online purchases pay peanuts relatively but will occasionally have additional discount codes and deals that might cover delivery costs etc so often still worth doing.

Quidco here too, I had just under 1k back over the last few years.
I almost gave up on a cashback for car insurance which had not tracked properly but logged ticket via Quidco support and received £180 back in the end.
